   Hi dear community,

   I try to get the following to work:
   

   function xxx_filter_cat()
   {
   	if (is_author()) query_posts("cat=4");
   	if (is_front_page()) query_posts("cat=2,3");
   }
   
   add_action('rss2_head', 'xxx_filter_cat');

   It should alter the rss2 feed, depending if it should generated for the general homepage, or for a single user.

   But: It doesn't work at all - is_author and all the others is_* functions I tried always trigger false. is_feed works, but well, doesn't help me very much.

   So: How can I determine the request inside the rss feed?

   Thanks in advance!

   is_author and is_XXX type functions (generally) check to see if there is a set query var..

   So author would be a query like.

   yoursite.com?author=pampfelimetten
   yourstei.com/author/pampfelimetten

   Depending on your permalink settings.

   Hi t31os_

   thanks for your answer!

   The problem is: They do work at:
   yoursite.com/author/pampfelimetten

   but NOT at:

   yoursite.com/author/pampfelimetten/feed

   Which, in my humble opinion is a bug.

   I can alter nearly every part of wp, and I think I should be able to alter the feeds of authors, categories, etc... independent to each other.

   Is this on a test site or one i can see?

   If you're using a local install, print out your rewrite rules so you can check they exist..
   

   <pre><?php print_r( $wp_rewrite->rules ); ?></pre>

   localhost/author/admin/feed/ - works as expected for me..
   or
   localhost/author/testuser/feed/ - also works

   Perhaps you should try a pre_get_posts filter for managing the categories on feeds though..

   @t31os:
   I wrote a workaround, also see trac ticket:
   

   function xxx_filter_rss()
   {
   	$uri= explode("/", $_SERVER['REQUEST_URI']);
   	if ($uri[1]=="author") {
   		global $wpdb;
    		$name = $wpdb->get_var("SELECT display_name FROM $wpdb->users WHERE user_nicename='".$uri[2]."'");
   		query_posts("cat=2,3&meta_key=xxx&meta_value=".$name."&showposts=10");
   	} else {
   		query_posts("cat=2,3");
   	};
   
   }
   add_action('rss2_head', 'xxx_filter_rss');

   I still think that there should be a better way to do stuff like that.
